Associated Analytic Story

How To Implement

This search is specific to Okta and requires Okta logs are being ingested in your Splunk deployment.

Required field

  • _time
  • displayMessage
  • client.geographicalContext.country
  • client.geographicalContext.state
  • client.geographicalContext.city

Kill Chain Phase

Known False Positives

None. Account lockouts should be followed up on to determine if the actual user was the one who caused the lockout, or if it was an unauthorized actor.
